IMPROVED APPARATUS FOR PRESERVING- FRUIT.

The Schedule referred to in these Letters Patent and making part of thesame.

Lblall 'whom it may concern: n

Be it known that I, C. C. WILLIAMS, of Brooklyn, inthe count-y ofKingsand State of New York, have invented a new and useful lmprovementinFruit-Preserving Apparatus; and I do hereby declare that the followingis a full, clear, and exact description, thereof, which will enableothers skilled in the art tou-lake and use the same, reference being hadto the accompanying drawing forming part of this specilication.

Figure 1 is a top view of my improved apparatus.

Figure 2 is a detail vertical section ofthe same, ta,- .ken through theline a; a', iig. 1.

, The invention consists in certain improvements 11pontle\'ices used inthe,preservation ot' fruits, and particularly thatfportiou thereof whichrelates to the transmission of steam from the boiler to the jar.

A is -the main part of the boiler, which 1 prefer to make in the shapeot'aitruncated cone.

Around the lower part of the boiler A is formed a shallow extension, B,made continuous with the boiler A, and the top of which is made dat, toserve as a sheli'to supportthe cans or jars while being heated, and.which being iilled with boiling water, assists in heating the bottomsor lower parts of the cans or jars.

The extension B is provided with au upwardly-extending lange or rim, b,to keep the cans or jars-in place while being operated upon.

The boiler A may, if desired, b e made without the vextension B, but inthis case it should be provided with a ring-shelf', fitting around thebase of the boiler to receive the jars or cans.

In'the top ofthe boiler A is formed a circular open-- ing, which shouldbe made large enough to receive the hand for convenience in keeping theinterior of the boiler perfectly clean.

Around the opening in thetop of the can is formed an upwardlyprojectingflange., C, having a screwthread formed upon its outer surface toreceive the screw-thread of thecap D.

The yjoint between the cap D and the top of the boiler is 'madesteam-tight, by a rubber or equivalent paeking,`E, placed around t-heflange C, and inter'- posed between the lower edge of the cap D and thetop of the boiler A.

F are radial pipes, the inner ends of which enter the cap D, andcommunicate with the interior of' the boiler A throughv holes in thebottom of said cap.

The series of radial pipes F rests upon an upwardlyprojecting flange,formedaround the top of the boiler A, as shown in fig. 2.

Upon the ends of the pipes F are formed, or to them are attached, shorttubes or sheaths G, to lreceive the upper ends of the pipes H, which arebent, so as to extenddown along the sides ofthe boiler A,

and enter the jars or cans, said pipes being made of such length as toreach to the bottom of said jars or cans, and having openings in thesides of their extreme lower ends, and Ithere only, so that the steammay be introduced into the jars or cans at their bottoms, thus insuringthc contents of said jars being heated in all their parts, which is notthe case when thesteam is introduced higher up in said jars or cans.

The joint between the pipes F and II is made steam-tight by short rubbertubes I, placed upon the outer ends of thepipes F, and through the outerends ofwvliich the upper ends of the pipes .H are introduced into thesheath G, attached to the said pipes F.

J are plugs, connected to the top tlauge of the boiler A, by shortchains, and which may be inserted in the outer ends of the pipes F, toprevent the escape of Athe steam when the pipes H are detached forconvenience `in placing or removing the jars or cans.

A small opening should be made iu the top ot' the boiler' A, closed witha cap or other suitable stopper, for convenience in introducing hotwater, if required, during thc operation of canning the i'ruit.

The. lower part of' theboiler A may be provided with a stop-cock, a',for convenience. in drawing oti" water when desired.

In using the apparatus, it is set upon the top ot a range,kitchen-stove, or upon a gas or oil-stove, as may be most convenient. y

The cans or jars, previouslytilled with the fruit or other substancelfor preserving, are arranged upon the extension or sheli' B, andV thepipes introduced into them and coupled to the pipes F.

As the steam is formed, it is discharged through the openings in thelower ends of the pipes H into the jars or cans, close to their bottoms,and permeating their entire contents, speedily heats them sufficiently.

As soon as one of the cans is ready, the pipes H F are uncoupled,and theopen end ot' the pipe F closed with one of the plugs J, allowing the jaror can to be removed, sealed, and rcplacedby another jar, and so on,without disturbing the. process ot' heating thel others.

In case all or several of the jars or cans are ready to be removed atthe same time, the plugmay bc left out of the pipe F of the can firstremoved, allowing the steam to escape, and holding all the cans heatedto the same point.

, I am aware that a patent granted to W. D. Brooks, July 2, 1867, for amachine involving the general principles ot' the machine abovedescribed, and v therefore I layy no claim to the apparatus itself, butsimply to certain improvements thereon.

Having thus described 'my invention,

l claim as new, and desire to secure by lLetters and air-excludingsleeves G, as and for the purpose Patentspecified.
